Why do mobile phones need to change their numbers when sending text messages?

Many people have overdue online loans and have been harassed by violence. Then they change their mobile phone numbers, and the result is constant reminders. Why? Why does the new phone number still receive these messages when it is clear that the phone number has been changed? Is collecting really a skill to know all your information? Why don't you come with me to see what happened?

The netizen's chat record shows that she borrowed an online loan, which was overdue, and her mobile phone card was replaced with a new one, and she could also receive a text message from the online loan.

Look at this short message. It's a short message notification of deduction failure from a loan platform. You can see that the short message shows that the automatic debit of the bank card with the tail number of 778 1 failed, prompting the active repayment. So is it possible that this new calling card is the reserved mobile phone number of the bank card? Netizens ruled out this possibility. Is it possible that this calling card was handled with her own ID card, or was collected by illegal means? This may also be ruled out, because this number is handled with her husband's ID card.

So is it possible that her husband's number is a good friend of the address book, and this short message is just a group short message? As a result, the other party's answer was surprising: this number is a new number with her husband's ID card.

In the Internet age, personal privacy is easily leaked through social media, shopping websites and other platforms. Maybe she leaked the information of this new mobile phone number in some channels, or maybe the collector got her latest information through some unknown illegal means. Through what channels did Ji get her latest mobile phone number? I'm afraid only the sender knows.

How to prevent information leakage?

1. Never enter your identity information, bank card information and personal data on a strange website.

2. Don't post your private photos and contact information on social platforms such as Weibo, WeChat and QQ Space. To prevent them from being used by criminals.

3. Don't click on the WeChat link and SMS link sent by strangers, otherwise it will be easy to catch the virus and cause property losses.

4. Regularly modify the passwords of social accounts and bank cards.

5. After receiving the verification code sent by a strange short message, the strange phone calls you for the verification code. Never give it.

6. When sending and receiving express delivery and handling banking business, remember to destroy the above address, name, contact information and other information before discarding it.

There are many traps and tricks on the Internet that we can't guard against. If you are not careful, you will be caught, and information leakage is worthy of vigilance!
